Police have released CCTV footage of a man they want to speak to following a ‘highly unusual’ sexual assault on a 15-year-old at Preston bus station.

The man featured on these CCTV images is understood to have engaged the girl in conversation at around 8.30pm, last Tuesday, before asking her for a light for his cigarette while inquiring as to whether or not she had a boyfriend.

It is alleged he then offered the girl £10 to go for a ride in his car with him while attempting to stroke her thigh.
